There is an increasing interest in reporting subscores, both at examinee level and at aggregate levels. However, it is important to ensure reasonable subscore performance in terms of high reliability and validity to minimize incorrect instructional and remediation decisions. This article employs a statistical measure based on classical test theory…

The primary purpose of this research was to adapt the Dimensions of Learning Organization Questionnaire (DLOQ) from Watkins and Marsick (1993, 1996) and examine its validity and reliability in a Korean context. Results indicate that the DLOQ produces valid and reliable scores of learning organization characteristics in a Korean cultural context.…

The potential for response variability to serve as an endophenotype for attention deficit hyperactivity disorders (ADHD) rests, in part, upon the development of reliable and valid methods to decompose variability. This study investigated the specificity of intra-individual variability (IIV) in 53 children with ADHD by comparing them with 25…

Background: Traditional health measurement tools use a pathogenic, or disease origins framework, to assess for the absence of disease or risk factors. Good or positive health, however, is more than the absence of disease and current tools do not reflect this. Purpose: The purpose of this study was to test the psychometric properties of the adult…

This study investigated the validity and reliability of the Turkish version of the Scales of Psychological Well-being (Ryff, 1989a). The sample of the study consists of 1214 university students. Results of language equivalency showed that correlations between the Turkish and English forms were 0.94 for autonomy, 0.97 for environmental mastery,…

We report the development of the Assessment of Individual Motives-Questionnaire (AIM-Q), a new instrument based on an evolutionary psychology theory of human motivation. It provides multitrait-multimethod (MTMM) assessment of individual differences on 15 motive scales. A total heterogeneous sample of N = 1,251 participated in eight studies that…

Among the academic community, there is a perception that there is an upward shift in grade point average over an extended period of time without a corresponding increase in achievement. This trend has become an alarming topic among educators, industry and the general public. Some attribute increases in GPA to improvements in student quality while…

Over the past several years, educational leaders and researchers have tried to find the causes for high school dropout. Studies have shown that both demographic and student factors have contributed to placing a student at risk for dropping out of high school. Most of the studies, however, have been conducted in urban or suburban settings.…

An alternative derivation of Tryon's basic formula for the coefficient of domain validity or the coefficient of generalizability developed by Cronbach, Rajaratnam, and Glaser is provided. This derivation, which is also the generalized Kuder-Richardson coefficient, requires a relatively minimal number of assumptions compared with that in previously…

Items for a morale scale were selected from Pace's College and University Environment Scales (CUES). The initial morale scale of 55 items was reduced to 22 items without substantially changing the dimension being measured. The scale discriminates among the 100 colleges in Pace's national sample, and its reliability is acceptable. The items-scale…

A critical review of systems of scoring multiple choice tests is presented and the superiority of a system based upon elimination method over one based upon the best answer mode is hypothesized. This is discussed in terms of the capacity of the mode to reveal the relationships among decoy options and the effects of partial information,…

A FORTRAN program for maximizing and cross-validating split-half reliability coefficients is described. Externally computed arrays of item means and covariances are used as input for each of two samples. The user may select a number of subsets from the complete set of items for analysis in a single run. (Author/JKS)

Describes some of the theoretical bases for the Affective Sensitivity Scale and reports research data on revisions that have been added since 1970. Proposes theoretical constructs to explain the role of affective sensitivity in the process of empathy. (Author/ABB)
